  • Free Supercharging makes long distances cheap and viable
  • It’s an EV, so it’s clean in terms of primary emissions

Although it’s an expensive car to buy in the first place, Tesla Model S running costs are low. Tesla itself suggests that a typical overnight charge on a domestic electrical main with a Type 2 plug would cost approximately £10.00, not bad for a real world range of 300+ miles.

When charging the Model S in a public car park or at one of Tesla’s Supercharger stations, the cost is free, save for any charge for parking charges you may incur As the Tesla itself does not produce any CO2 emissions, all versions of the Model S fall into VED car tax band A, meaning it’s likely to be free for the foreseeable future.

The more interesting aspect of Tesla Model S ownership is that if you run it purely on a free Supercharger, the fuel savings can be considerable. The upshot of this is that if you’re paying monthly, you can run it for the same cost as much more humble cars (due to spending zero on petrol and diesel). Never has the sticker price of a car been less relevant than here.

Tesla reliability

Any car has the potential to break down but the company’s reputation in this regard is a bit flaky. Problem areas with older cars include the quality of the paintwork and interior trim as well as issues with bespoke items such as its doorhandles, climate control systems and the infotainment system. Warranty cover usually encompasses this, but dealer service and supply can be slow,

There are fewer moving parts than on a conventionally-engined cars and electric motors are proven to work with a greater level of reliability than internal combustion engines, and this is largely the case with the Model S – it has suffered one or two motor failures over the years. Although Tesla has been responsible for the ongoing development of the Model S and reliability is improving, it did have a headstart as some of the early work was undertaken in conjunction with Mercedes-Benz.

Fewer moving pieces of switchgear also mean there’s less to break and come loose. That said, the 17-inch touchscreen could prove costly to repair if the electronics behind it fail.
